How long you got to call mistrial?

The time to call a mistrial can vary depending on the jurisdiction and the specific circumstances of the case. Generally, a party can request a mistrial at any point during the trial when they believe a fundamental error has occurred that affects the trial's fairness. However, it’s typically advisable to raise the issue as soon as the grounds for the mistrial become apparent. Courts may have specific rules governing the timing and procedure for such requests.
